Manage symbol libraries

Libraries contain the symbols that diagram parsing uses to detect objects in engineering diagrams. You can create or modify libraries to add new symbols or geometries of an existing symbol.

Add a symbol to a library

1. Navigate to Data management > Contextualize > Diagram parsing.

2. Select Manage libraries > and the library to which you want to add the symbol. To create a symbol library:

   1. To copy a library template, select ⋮ > Duplicate template.

   2. Select + to create a new library.

3. Select Open file and open the file containing the symbols you want to add. We recommend using legend files containing a set of symbols.

4. To select the symbol you want to add, drag and move the cursor to select the symbol or use the keyboard shortcut: Shift while you drag to select a symbol.

5. Specify which Asset class (for example, Pump) and Asset type (for example, Centrifugal) the symbol represents.

6. To add a geometry to an existing symbol, select the symbol and Add as geometry.

Note

For pipe detection, a line is identified as a pipe only if it has an endpoint touching at least one detected symbol. Adding more geometries of piping symbols does not affect the detection process. When you review the parsed output, adding lines as pipes will create additional detected pipes from the selected lines.

Important

When you delete a symbol from the library page, the symbol is deleted from every file using it. When you delete a geometry from the library page, this shape of the geometry won't be identified as a symbol for parsing diagrams in future parsings.
